Safety of machines or systems

The safety of the machine or system and of the application in which the machine or system is
used is the responsibility of the machine/system manufacturer and of the operating company.
In order to use the system described in this document with the associated safe function blocks,
you must have drawn up an appropriate safety concept for your machine or system. This
includes the hazard and risk analysis, among others, according to the directives and standards
listed in chapter "Directives and standards" on page 13.
The target safety integrity level is ascertained on the basis of the risk analysis.
– SIL acc. to IEC 61508
– SILCL acc. to EN 62061
– Cat./PL acc. to EN ISO 13849-1
The following are dependent on the ascertained safety integrity:
– The wiring of safe sensors, command devices and actuators within the overall safety func-
tion
The use of safe function blocks in the safety logic. 
–
The safety logic is created using the MSIsafesoft configuration software.
For the sensible use of the MSI 100/200 system, provide the machine with safety-related
equipment.
This includes, for example:
– E-Stop buttons
– Protection hood switches
– Enabling switches
– Light barriers
Carry out a validation every time you make a safety-related modification to your overall sys-
tem.
Use the relevant checklists when carrying out the validation. Enter the details requested in the
"Project Information" dialog box in the MSIsafesoft safe configuration software.
Use your test report to satisfy yourself that:
– The safe sensors and actuators are connected correctly in the MSI 100/200 safety appli-
cation. To do this, use the "Wiring check" function in the MSIsafesoft configuration soft-
ware.
– The inputs and outputs of the safety modules and the safe extension modules are cor-
rectly configured.
– The signals have been connected to the safe sensors and actuators correctly (single-
channel or two-channel).
– Cross-circuit detection is implemented in your application, if required (see page 22).
– All safe function blocks and functions in the MSIsafesoft configuration software are con-
nected correctly.
